HTML5 Validity: <time> tag in node.tpl.php

Hello

The output of the time tag in note.tpl.php seems to be invalid. It needs to have either valid formating withing the time tags or it needs to have the datetime attribute in the right format, in wich case the thing within the time tags can be how ever it likes to be. element desc. at htmldoctor

page.tpl.php line 37

In my personal subtheme I allready fixed this problem this way:

<?php
<time datetime="<?php print format_date($created, $type = 'custom', $format = 'Y-m-d\TH:i:sP') ?>"><?php print $date; ?></time>?>

<time datetime="2012-06-13T22:05:31+02:00">Wed, 06/13/2012 - 22:05</time>

This is valid.

Thank you
